Property tax is the largest line item no one audits.
For most commercial real estate portfolios, property tax is the #1 operating expense, and the only one nobody underwrites at a parcel level. Every cycle, billions are quietly overpaid. The problem isn’t that owners don’t care. It’s that no tool was ever fast enough or precise enough to find it.
Four steps. One outcome.
Upload your portfolio. Our AI-native engine scans every parcel, flags over-assessment, and licensed counsel files the appeal. Under 7 minutes of your time, then we handle the rest.

Status flows back the moment the board rules. We invoice only on the reduction we won.
An automated valuation model built on assessor rolls, comparable sales, and income data finds property tax over-assessment across commercial, multifamily, industrial, retail, and office portfolios. See the dashboard
Every assessment appeal tracked from drafted to filed to settled, with evidence packages, e-signatures, and a direct line to counsel per parcel. See the pipeline
Assessed values, certified tax rolls, and appeal deadlines read straight from county assessors and appraisers, refreshed as rolls certify and notices mail. How we source data
Every win trains the next one.
Reserve’s machine learning models are trained on successful commercial property tax appeals: the comparables, evidence, and arguments that actually won reductions in front of real assessors. Every appeal Reserve Tax Group wins feeds back into the AVM, so the platform keeps learning what moves each county assessor and each jurisdiction. The more we win, the sharper the next filing gets, a compounding accuracy advantage traditional property tax firms cannot match.
The automated valuation model learns from real property tax reductions that cleared, not theory. Every valuation is anchored to comparables and assessment appeals that have held up before county boards and value adjustment boards.
Because Reserve tracks what persuades each assessor and jurisdiction, every appeal is built around the evidence that specific office responds to, across multifamily, industrial, retail, and office property tax.
Each reduction Reserve secures makes the next filing smarter. The property tax appeal success rate climbs as the dataset grows, so owners who join now inherit every win that came before.
The model flags it. The county agrees.
Reductions from the 2026 Florida appeal season. The AVM flagged each parcel, Reserve Tax Group built the income evidence, and the Property Appraiser accepted the reduction before any Value Adjustment Board hearing. Owner names and parcel identifiers are withheld to protect client confidentiality.
Large-format retail. Income analysis submitted by Reserve Tax Group; the Property Appraiser found the data supported a reduction to the building value.
Large-format retail. Building value revised at informal review to stay consistent with the prior year, with no hearing required.
Single commercial property. Nearly a quarter of the market value taken off the roll, carried into every future year the owner holds the asset.
Values are from Miami-Dade and St. Lucie County Property Appraiser 2026 records. Value removed combines assessed value for the Miami-Dade parcels and market value for the St. Lucie parcel. Miami-Dade tax savings are estimated by applying each parcel’s local millage to the reduction in taxable value; actual savings depend on final adopted millage rates. Past results do not guarantee future outcomes.
